Asynchronous Support

Browse Source 
scp.c, scp.h
	- added sim_uname (Unit Name) API to simplify places which might want to display it (mostly debug messages).
	- added support for clock co-scheduling
	- added debugging to trace event queue activities

    sim_defs.h
	- added support for clock co-scheduling
	- added support for sim_uname (Thread local storage macro)
	- added support for debugging to trace event queue activities
	- simplified debug code by using sim_uname
	- fixed support macro for sim_is_active when asynch timers are in use

   sim_rev.h
	- fixed nested comments

    sim_tmxr.c, sim_tmxr.h
	- added support for clock co-scheduling
	- simplified debug code by using sim_uname
	- added support for devices which poll for output on different units

    sim_timer.c, sim_timer.h
	- added support for clock co-scheduling
	- fixed asynchronous clock calibration to smooth out calibration adjustments
	- simplified debug code by using sim_uname
	- added ability (when running with asynchronous support) to explicitly disable or enable asynchronous timer support.
	- changed sim_timer_inst_per_sec to return a double value since the result is always used in a double expression and integer overflow could occur under strange timing conditions

    vax/vax_stddev.c
	- converted from simulator specific clock co-scheduling to generic clock co-scheduling.

    vax/vax_cpu.c
	- added EVENT and ACTIVATE debug flag (SET CPU DEBUG=EVENT;ACTIVATE) support

    pdp11/pdp11_dz.c
	- converted from simulator specific clock co-scheduling to generic clock co-scheduling.

    pdp11/pdp11_vh.c
	- converted from simulator specific clock co-scheduling to generic clock co-scheduling.

    pdp11/pdp11_xq.c
	- converted from simulator specific clock co-scheduling to generic clock co-scheduling.
